Hi all,

I was looking for a crisp vintage Omega dress watch for a while now and I stumbled upon someone offering me the Omega OT 2180 for 5000 US dollars. It seems in excellent condition. The watch is the 18k gold variant with a 35.5mm case, produced in 1947, running the 30T2 mechanism. I absolutely love it. But I do have some reservations (given the high price) and I hope this community can help me make sense of it.

• First, the current owner claims the dial has not been redone, and that the watch was essentially sitting in box, being barely worn, almost to be considered new old stock. The dial does show some small dots of ageing, but I find it hard to believe that it still looks this clean for a watch from 1947. How would a repainted dial affect the value of the watch for collectors?
• Second, the watch comes with an Omega signed crown. I am not sure if these already existed in 1947, I assumed that Omega back then used non-signed crowns?
• Third, the strap and the buckle are generic. I believe these watches used to come with gold plated Omega buckles. How does this affect the value?

It is one of the most beautiful dials and watches I have seen, but given the price, I am doubting. Can someone with knowledge on the 2180 tell me how many of these were made, specifically how many versions in 18k gold with a white/silver dial?

Thanks.

We cannot think without pictures. I can’t comment on some of your questions without them.

I will tell you that $5,000 for any 18K Omega 30mm watch is outrageous, unless the bracelet is also 18K gold and very heavy.

Apologies, I thought I added the pictures to the post.

If you consider that price outrageous, what do you think would be a fair price?

and by 30mm, I assume you mean the movement diameter, because the case is 35.5mm?

The price is ridiculous. I also think the dial has been repainted. I can't point to anything specific, it just doesn't look right.

Looks like a redial. Indice at top of sub-dial intrudes into the dial proper. Minute graduations are not very uniform. "Omega" font is unlike known 1940s renderings of the brand name.

Only an opinion.

Dial is definitely not original. Logo is from 1970’s or 1980’s. Hands and crown could be original.

IMO, watch is worth gold value of case (without crystal or movement) plus $150 or so for movement.

Exactly this.

@arakatamasu Be very aware with this seller going forward. With the price he’s asking I don’t believe for a second he doesn’t know the dial isn’t legit.

Just to answer the last of your questions above: The absence of the original buckle is common and not a big deal in terms of price. In fact, since 99% of them don’t have the correct buckle anymore, it’s more like its existence is a bonus.

And a redone dial always destroys the value to collectors. Which is why @gatorcpa says gold value + parts value. I wholeheartedly agree.

Great advice, do you know how much the gold case could be worth? And the movement would only be 150 USD? I expected the movement to be more expensive....

You will only know when everyting has been removed from the case (crystal/movement/crown/stem/springbars) and the case weighed.
Then, when you have a valid weight you can shop around your local gold buyers to see how much they will offer.

There is probably around 10g of 18k gold there as that is a slender case. That’s about a grand in USD.

Case weights vary. The fat lug Seamasters are in the mid 20s of grams but that one is much more slight. Not sure why you care. Walk away from it.

Because there are hundreds out there in varying states of repair, harvested from gold watches just like this. The only market for these spare movements are watchmakers who need parts.

However, for a movement as common as a 30mm Omega, it is easier for watchmakers to call their parts supplier and get exactly what they need for a job rather than purchase a whole movement and hope that the part they need is still good.

This watch has no collector value whatsoever.
